20 Claims.

This invention relates generally to braiding machines and more particularly to "ahovel combina tion housingand collector construction including a receptacle arranged to'collect andretainfcentrifugally discharged deposits of yarn 1int,-dust',

loose grease and other substances.

Braiding machines oflthe slow speed t pe have generally been operated without guards or protiori of the machine; and disturbance of the loose lint, and other particles 'withinthe machine by the swirling blast of air caused by the swiftly rotating .25. machine members, caused the'particles to rotationally swirl also, and become more'or less firmly lodged in the machine parts, thereby necessitating .frequent stopping of the machine. Theselodged particles then hacl'to be blown out of thema- 130i chine by a blast of compressed air from a separate source. 7

It is an objectof this inventionto provide a novel housing arranged to utilize the air blast created by the moving machineparts internally 35.01 the housing for the centrifugal discharge of loose particles of dust, lint and other substances through a discharge port or outlet provided in the housing, so that such particles may become separately accumulated outside the machine and 40. lodged within a removable receptacle positioned adjacent to the exhaust port or outlet.

Another object is to effectively utilize, within the housing of a braiding machine; means constituting part of the machine to produce currents caus- 45 ing the air to swirl in a circular path to centrifugallydischarge extraneous material through suitable openings provided in the housing.

Another object is to provide a braiding machine with a detachable receptacle; arranged to. receive discharged lint and other particles from the braiding "machine housing and to permit convenient removal and cleaning of such receptacle.

With these and other objects in view, which will become apparent; from the following detailed deg invention shown i'n the accompanying drawings,

my inventionresides in the novel elements or" constructionymechanisms and combination of parts in cooperative relationship; as hereinafter more particularly pointed out in the claims.

In the accompanying drawings:

Fig. l is a top plan view of a braiding machine equipped with the present novel enclosing housing.

Fig. -2 is a side elevation of the same partly broken away.

Fig. 3 is a. view in transverse section through the braiding machine and housing, taken substantially along the line 33 of Fig.

Fig. 4 is aperspectiveview of the detachable receptacle orcontainer. I

With reference to the drawings, Fig. 1 illustrates a' braidin machine housing suitably secured to atable or base 11 which is mounted ona 'suitableframelil. A receptacle 13 is re movably, secured to the housing, adjacent to a discharge 3outletcoriduit 14 projecting from the housing in a direction facilitating the flow of an air draft from thehousing, a bracket 15, fixed to the table or base 11, being provided for this purpose. The housing lo'preferably comprises a dome shaped top member or shell 16 suitably secured to a cylindrical body portion l'lby means of an: upper ring member 18 as disclosed in ,Fig. 2. A circular angle bar 19 is fixed to the lower portion 20 of the housing body 17 for securing the housing 10 to the'table 11.

At'one portion, of the housing, there is provideda pivoted and slidabledoor member 21 for covering an access opening "22 to the braiding mechanism 23. The door 21 is pivotally connected to a vertical bearing 24 atthedomecenter, and hasits lower end 25slidable in a track 26 formed on the lower portionZO of'the braiding machine housing. A'handle2l is provided for sliding the door 21 relative to the housing in effective opening and closing of the door. Also, the door may be arranged to cooperate with a suitable safety switchto normally prevent operation'of the braiding machine when the door is open.

A. braidtake-off winding reel 2'7 is fixed to a gear 28 on a shaft 29 which is journaled in a pair of upright standards 30 on the base 11. The reel 2 7 revolves simultaneously with the gear 28 to wind the finished braided product 31. A small end gear 321s fixed upon acountershaft 33 anddrives another gear (not shown) which engages and; drives the larger gear 28.

The braiding mechanism 23,'a portion of which 5 Air inlet ports or openings 36 are provided in the housing shell for permitting a sufiicient amount of air to be drawn into the housing by suction to aid in the discharge, through the discharge port or conduit 14 is disposed substantially tangentially to the cylindrical side-wall body portion of the housing, of extraneous material created or dislodged during braiding operations.

The braiding operation in this instance is to cover a core element, such as a wire or a group of strands 37, by the yarns from upper and lower oppositely revolving yarn packages 38 andBQ. This element 37 approaches the braiding mechanism 23 from below the table or base 11, passes upwardly through the machine to an outlet 40 at the top of the housing, and is continuously wound from the outlet 40 onto the take-off reel 27, as shown in Fig. 1.

Air pressure is created within the housing by the swiftly revolving groups of yarn packages and machine parts, the velocity of the air being increased by the impeller like structure of radial arms 41.

The yarn packages 39 are mounted in a group on radially positioned spindles, which group revolves in a horizontal plane and in aclockwise direction, as viewed in Fig. 3. The yarn packages 38 are radially mounted in a group above the yarn packages 39, but rotate in a counterclockwise direction, for interwinding the strands from that group of packages in a reverse direction on the element 37. Each of the radial arms 41 in this instance includes a portion 42 which impels the air within the'housing to increase the velocity of the rotating air blast for expelling particles of dust, grease and lint from the housmg. I

Fig. 3 discloses .a plan view of the braiding machine mechanism 23 enclosed by the housing shell 16. Only one yarn package of the upper group is here shown, in order to reveal the similar fan like position of the lower group of yarn packages 38, which are supported on spindles 43. The yarn packages 38 traverse an annular track 44, having rollers 45, during their revolution, a turret (not shown) being provided for the revolving packages 39. The yarn is fed from the packages 38 and 39 in a well known manner which provides that the yarns become interbraided while being wound upon the element 37.

The swirling action of the enclosed air is indicated by arrows 46. The cooperative relation of the oppositely rotating yarn packages is such that the air blast is directed toward the exhaust port 14 for exit therethrough and deposit within a wire mesh structure 47 of the receptacle 13 of any extraneous material entrained with the moving volume of air.

The body portion of the collector receptacle or container 13 is preferably constructed of wire mesh fabric as seen at 47, though anyopenwork or foraminated material may be used if desired. The mesh body 47 is secured to a skeleton framework 53, by means of bolts or rivets 48. Top and bottom covers 49 and 50, respectively, are provided for the receptacle .13. The upper cover 49 is also made of wire mesh but has a substantially annular frame 51 for encompassing the upper end of the wire-mesh side wall of the body. A portion of the cover is preferably straight, as seen at 59 across the top of the open front po s tion of the receptacle. The bottom cover 50 is circular and flat and includes a flange 52 to receive the lower end 53a of the side-wall frame 53. In Fig. 4 the mesh 47 is shown broken away at 47a to more clearly show the construction of the lower end 53a of the receptacle frame 53.

A wall 54 is in the path of the air blast and functions as a shield to prevent the discharge of lint and 'dirt against the gears and other machine parts located in the vicinity indicated at 55. This wall 54 may be suitably cut away, as seen at 60 to conform to adjacent parts of the machine. The wire mesh body 47 is adapted to efficiently retain the lint and other particles while permitting the air to pass through the collector. A certain amount of grease and oil may be carried by the air to cover the mesh structure and assist in holding the lint and other particles within the collector.

The upper part of the bracket 15 is formed hol low to receive and support the collector 13 and the outer wall of the housing 17 is provided with headed studs 56 to receive the hooked portions 57 of the wall 54, provided at the outer end whereby the collector is properly secured in position at the discharge opening 41. When an excessive amount of lint, dirt and the like has accumulated in the collector 57, the latter is simply lifted off the studs. The top cover 49 may also be removed to facilitate emptying and cleaning the collector. The housing 10 is readily attached to or detached from the base 11 by means of the bolts 58. Also, while here shown as circular in form, the housing may be of any suitable shape to accommodate the braiding mechanism 23.

- The present invention is not limited, in its application, to braiding machines, but is useful in connection with any, machine having rotating parts which produce detritus of any kind.
